ITER is an international collaborative project under development by nations representing over one half of the world's population. Major components will be supplied by "Domestic Agencies" representing the various participating countries. While the supervisory control system, known as "CODAC", will be developed at the project site in the south of France, the EPICS and PLC-based plant control subsystems are to be developed and tested locally, where the subsystems themselves are being built. This is similar to the model used for the development of the Spallation Neutron Source (SNS), which was a US national collaboration. However the far more complex constraints of an international collaboration, as well as the mandated extensive use of externally contracted and commercially-built subsystems, preclude the use of many specifics of the SNS collaboration approach which may have contributed to its success. Moreover, procedures for final system integration and commissioning at ITER are not yet well defined. This paper will outline the particular issues either inherent in an international collaboration or specific to ITER, and will suggest approaches to mitigate those problems with the goal of assuring a successful and timely integration and commissioning phase.

Experience has shown that imaging software and hardware installations at accelerator facilities need to be changed, adapted and updated on a semi-permanent basis. On this premise, the component-based core architecture of Video System 3 was founded. In design and implementation, emphasis was, is, and will be put on flexibility, performance, low latency, modularity, interoperability, use of open source, ease of use as well as reuse, good documentation and multi-platform capability. In the last year, a milestone was reached as Video System 3 entered production-level at PITZ, Hasylab and PETRA III. Since then, development path is stronger influenced by production-level experience and customer feedback. In this contribution, we describe the current status, layout, recent developments and perspective of the Video System. Focus will be put on integration of recording and playback of video sequences to Archive/DAQ, a standalone installation of the Video System on a notebook as well as experiences running on Windows 7-64bit. In addition, new client-side multi-platform GUI/application developments using Java are about to hit the surface. Last but not least it must be mentioned that although the implementation of Release 3 is integrated into the TINE control system, it is modular enough so that integration into other control systems can be considered.

The Accelerator Control System at Fermilab has evolved to enable this relatively large control system to be encapsulated into a "box" such as a laptop. The goal was to provide a platform isolated from the "online" control system. This platform can be used internally for making major upgrades and modifications without impacting operations. It also provides a standalone environment for research and development including a turnkey control system for collaborators. Over time, the code base running on Scientific Linux has enabled all the salient features of the Fermilab's control system to be captured in an off-the-shelf laptop. The anticipated additional benefits of packaging the system include improved maintenance, reliability, documentation, and future enhancements.

We have developed a large-bandwidth data acquisition (DAQ) network for user experiments at the SPring-8 Angstrom Compact Free Electron Laser (SACLA) facility. The network connects detectors, on-line visualization terminals and a high-speed storage of the control and DAQ system to transfer beam diagnostic data of each X-ray pulse as well as the experimental data. The development of DAQ network system (DAQ-LAN) was one of the critical elements in the system development because the data with transfer rate reaching 5 Gbps should be stored and visualized with high availability. DAQ-LAN is also used for instrument control. In order to guarantee the operation of both the high-speed data transfer and instrument control, we have implemented physical and logical network system. The DAQ-LAN currently consists of six 10-GbE capable network switches exclusively used for the data transfer, and ten 1-GbE capable network switches for instrument control and on-line visualization. High-availability was achieved by link aggregation (LAG) with typical convergence time of 500 ms, which is faster than RSTP (2 sec.). To prevent network trouble caused by broadcast, DAQ-LAN is logically separated into twelve network segments. Logical network segmentation are based on DAQ applications such as data transfer, on-line visualization, and instrument control. The DAQ-LAN will connect the control and DAQ system to the on-site high performance computing system, and to the next-generation super computers in Japan including K-computer for instant data mining during the beamtime, and post analysis.

Novosibirsk Scientific Center (NSC), also known worldwide as Akademgorodok, is one of the largest Russian scientific centers hosting Novosibirsk State University (NSU) and more than 35 research organizations of the Siberian Branch of Russian Academy of Sciences including Budker Institute of Nuclear Physics (BINP), Institute of Computational Technologies, and Institute of Computational Mathematics and Mathematical Geophysics (ICM&MG). Since each institute has specific requirements on the architecture of computing farms involved in its research field, currently we've got several computing facilities hosted by NSC institutes, each optimized for the particular set of tasks, of which the largest are the NSU Supercomputer Center, Siberian Supercomputer Center (ICM&MG), and a Grid Computing Facility of BINP. A dedicated optical network with the initial bandwidth of 10 Gbps connecting these three facilities was built in order to make it possible to share the computing resources among the research communities, thus increasing the efficiency of operating the existing computing facilities and offering a common platform for building the computing infrastructure for future scientific projects. Unification of the computing infrastructure is achieved by extensive use of virtualization technology based on XEN and KVM platforms. Our contribution gives a thorough review of the present status and future development prospects for the NSC virtualized computing infrastructure focusing on its applications for handling everyday data processing tasks of HEP experiments being carried out at BINP.

The production and exploitation of industrial control systems differ substantially from traditional information systems; this is in part due to constraints on the availability and change life-cycle of production systems, as well as their reliance on proprietary protocols and software packages with little support for open development standards [1]. The application of agile software development methods therefore represents a challenge which requires the adoption of existing change and build management tools and approaches that can help bridging the gap and reap the benefits of managed development when dealing with industrial control systems. This paper will consider how agile development tools such as Apache Maven for build management, Hudson for continuous integration or Sonatype Nexus for the operation of "definite media libraries" were leveraged to manage the development life-cyle of the CERN UAB framework [2], as well as other crucial building blocks of the CERN accelerator infrastructure, such as the CERN Common Middleware or the FESA project.

The LHC Access Safety System has introduced a number of new concepts into the domain of personnel protection at CERN. These can be grouped into several categories: organisational, architectural and concerning the end-user experience. By anchoring the project on the solid foundations of the IEC 61508/61511 methodology, the CERN team and its contractors managed to design, develop, test and commission on time a SIL3 safety system. The system uses a successful combination of the latest Siemens redundant safety programmable logic controllers with a traditional relay logic hardwired loop. The external envelope barriers used in the LHC include personnel and material access devices, which are interlocked door-booths introducing increased automation of individual access control, thus removing the strain from the operators. These devices ensure the inviolability of the controlled zones by users not holding the required credentials. To this end they are equipped with personnel presence detectors and the access control includes a state of the art biometry check. Building on the LHC experience, new projects targeting the refurbishment of the existing access safety infrastructure in the injector chain have started. This paper summarises the new concepts introduced in the LHC access control and safety systems, discusses the return of experience and outlines the main guiding principles for the renewal stage of the personnel protection systems in the LHC injector chain in a homogeneous manner.

The ubiquitousness of web clients from personal computers to cell phones results in a growing demand for web-based access to control system data. At the Oak Ridge National Laboratory Spallation Neutron Source (SNS) we have investigated different technical approaches to provide read access to data in the Experimental Physics and Industrial Control System (EPICS) for a wide variety of web client devices. We compare them in terms of requirements, performance and ease of maintenance.
